Polar Bear Welfare Under Climate Pressure

Polar bears are experiencing welfare impacts from climate change through reduced sea ice, longer fasting periods and increasing human-bear conflict as bears move closer to settlements.

Key Facts

Polar bear populations are projected to decline by 30% by 2050 under moderate climate scenarios due to sea ice loss in critical denning and hunting habitat
Arctic sea ice extent has declined approximately 13% per decade since satellite monitoring began in 1979 — a trend continuing despite year-to-year variability
Bears in Hudson Bay are coming ashore earlier and spending longer periods fasting as the ice-free season extends — fasting periods that compromise body condition for denning females
Human-bear encounters in communities including Churchill, Manitoba have increased as nutritionally stressed bears search for alternative food sources near settlements
Problem bear management programmes tranquilise and relocate or hold bears rather than killing them — reducing welfare harm while addressing safety
Orphaned polar bear cubs require 2-3 years of intensive captive care before release is possible — facilities are extremely limited

Welfare Considerations

Polar bears experiencing extended fasting, failed pregnancies and cub mortality due to climate-driven ice loss are suffering welfare consequences that can be measured in individual bears through body condition scores, cub survival rates and stress hormones. The mechanism — climate change reducing the ice platform bears depend on for seal hunting — operates through human emissions with a clear causal chain. Individual welfare interventions are possible (problem bear management, orphan care) but the scale of the problem requires systemic climate action that no individual bear welfare programme can substitute for. Supporting climate policy is therefore the most impactful polar bear welfare action available.

What You Can Do

Support climate action policies that commit to emissions reductions consistent with limiting Arctic warming — the most important polar bear welfare intervention
Donate to organisations monitoring polar bear health and providing evidence for climate policy including Polar Bears International
Support community-based bear coexistence programmes that reduce lethal conflict outcomes in Arctic settlements
Oppose trophy hunting of polar bears — already under pressure from climate, they cannot absorb additional human-caused mortality
